Final answer:
When two flowers with different traits are crossed, the proportion of offspring with red flowers can be predicted using Mendel's laws of inheritance. In this case, 75% of the offspring are expected to have red flowers.
Step-by-step explanation:
When two flowers with different traits are crossed, the offspring can inherit those traits in various combinations. In this case, 50% of the flowers are red and 50% are blue in the parental generation. Assuming a simple Mendelian inheritance pattern, where red is dominant and blue is recessive, we can predict the proportion of red-flowered offspring in the next generation.
Using the information provided, we can deduce that the parents are heterozygous for flower color, meaning they carry one copy of the red allele and one copy of the blue allele. When these flowers are crossed, there are three possible genotypes for the offspring: RR (red-flowered homozygous dominant), Rr (red-flowered heterozygous), and rr (blue-flowered homozygous recessive).
Based on Mendel's laws of segregation and independent assortment, we would expect a 1:2:1 ratio of the three genotypes in the offspring. Therefore, the proportion of offspring with red flowers would be 1(RR) + 2(Rr) = 3/4 or 75%.
